TYSONS, Va. (WUSA) - Doctors offices are seeing a surge in flu cases. At Tysons Corner Pediatrics, Doctor Farha Naqui says they've seen a number of flu cases in patients who did receive a vaccine.

Dr. Naqui says people should see their doctors as soon as they have flu symptoms which include headaches, fever, body aches, coughing, congestion and loss of appetite.

If tested positive for flu, the patient will be given a Tamiflu prescription which lessons the severity and the length of the virus.

Doctors say the reason people who have received the vaccine still get the flu is because there are always a few strains that are not covered in the vaccine. Getting vaccinated should keep you from getting the most severe forms which could land you in the hospital.

So far, schools in Fairfax, Loudoun, Arlington Counties and Alexandria have NOT seen a spike in absentees due to the flu.
